I changed the Linux copyright license to be the GPL some time in the first half of 1992. Mostly because I had hated the lack of a cheaply and easily available UNIX when I had looked for one a year before.

I will, in fact, claim that the difference between a bad programmer and a good one is whether he considers his code or his data structures more important. Bad programmers worry about the code. Good programmers worry about data structures and their relationships.

In science, the whole system builds on people looking at other people's results and building on top of them. In witchcraft, somebody had a small secret and guarded it - but never allowed others to really understand it and build on it. Traditional software is like witchcraft. In history, witchcraft just died out. The same will happen in software. When problems get serious enough, you can't have one person or one company guarding their secrets. You have to have everybody share in the knowledge.

Given enough eyeballs, all bugs are shallow.

Me trying to make a business around Linux would have been a total disaster.

Software is like sex: It's better when it's free.

Linux has definitely made a lot of sense even in a purely materialistic sense.
